TV, No picture but i have sound

Without getting all technical your LED backlights are bad, the part of unhooking one ribbon cable and not having the repeated cycle would be normal in this model set.

Have you tried unplugging it and letting it reboot?

Hi!


Check your power amp circuit. Or, check if it is feed by the power supply circuit. Good luck,


Serge.

Check and replace the back-light LED strip. Contact any service technician. http://electronicshelponline.blogspot.com/

Here is what to check when your TV is turned on, power light is ON, but no picture is seen or sound is heard:

1 - Be sure the component you are using (Xbox, Cable, SAT, ROKU) is turned ON.
2 - Check to be sure all cable and cords are securely connected to the TV inputs and component outputs.
3 - Make sure you are on the correct input as some TV's will show a black screen if there is nothing connected to that input.
4 - Unplug the input you are trying to use from the TV (such as an HDMI Cable) and plug it back in.
5 - Check for signs of damage on all cords and cables from the TV to all components.
6 - Make sure the TV is not in ENERGY SAVE MODE, press the button on the remote control to go back to normal mode.
7 - Unplug the TV for 10 minutes to see if there was a temporary one time issue with the TV.
8 - Disconnect the TV from power for 2 minutes, then when plugging it back in PRESS AND HOLD THE POWER BUTTON ON THE TV FOR 10 to 20 SECONDS to try and force the TV to reset.
9 - If after checking all these different issues, you may have a Faulty Power Supply Board, A Bad Capacitor on the Power Supply Board, Loose Wire Harness, or Loose Ribbon Connector in the TV itself.
10 - Most likely when a TV has the power light ON but NO PICTURE and NO SOUND, it is the Power Supply Board that has failed.

Same issue with - Panasonic TH-50PX70A , power UP with red standby, then power ON by remote - only Gives GREEN led blinking 35-40 times, followed by solid green led with no no picture no sound.
>> Solution; unplug Plasma from AC 10-15min, then plug in & power on to Red standby led,, At this point - Power ON tv while holding down both -Volume Down and F (function Select) buttons (front panel door) at the same time turns picture ON,all ok.

Hold down the menu and the input buttons on the front at the same time for 5 seconds. Led will flash a 2 digit code repeatedly. reply back with this code. If the set has been unplugged after failure code will be erased.
